heat treatment services for alloy and aluminium

Solution Treatment

This is a fundamental requirement for the strengthening of aluminium alloys. It entails the solid state dissolving of alloying elements into the aluminium. This is achieved at temperatures near to the melting point of the material, followed by a quench process to lock the dissolved alloying elements into place. Without this, the alloy cannot be strengthened. We have Nadcap approved ovens for the aircraft industry and CQI-9 compliant ovens for the automotive industry.

Rapid Quenching (Less than 10 seconds)

Immediately following solution treatment certain parts require rapid quenching. This involves a controlled quench in times of less than 10 seconds to ensure that quenched parts lose or expel minimal temperature between the furnace the quench bath.

Settings

This process removes the quench distortion from solution treated parts.

Fast heat transfer causes the thermal gradient in certain parts to twist during the quenching process. Alloy Heat Treatment can set to close tolerances in a tight time frame at quench stage.

This process can be extended to the rectification of parts distorted during general manufacturing.

Shot Blasting (Exclusively Aluminum)

Our Hanger Blast facility is used to give the product a uniform colour or appearance, such as a silvery matt finish, which will be visible in the finished product.

Precipitation Hardening

This heat treatment process is generally undertaken between 100 and 200 ºC and causes dissolved alloying elements to finely precipitate within the aluminium. This results in the alloy becoming harder and stronger. This process is time dependant, hence, the term “age hardening”.

Hardness & Conductivity Testing

We are able to verify the conformance and batch uniformity of heat treated parts, particularly for the aerospace industry. This is all done by level 2 certified operators using machines certified to UKAS standards.

Dye-Penetrant Inspection

This technique is used to detect cracks or flaws in heat treated parts. This is offered to customer requirements upon request.

Metallographic Inspection

Alloy Heat Treatment is Nadcap accredited for the micro examination and evaluation of heat treated parts in accordance with specific industry standards.

Degreasing

Our in house SED compliant solvent degreaser is capable of cleaning and drying components up to 3m long and 500 kilos in weight, to aircraft industry standards.

Mechanical Testing

Alloy Heat Treatment offers this as a standard sub contracted service.

Transport (Collection and Delivery Service)

We are able to offer a swift delivery or collection service via courier or haulage contractors to suit customer needs.
